Still using charge integral for PID #98

Closed gwm17 closed 2 months ago

gwm17 commented 4 months ago

Most everywhere we can we use the amplitude of the signal rather than the integral to represent the charge. The only real exception is in the particle ID, where dEdx is still calculated using the integral. It would be good to make this more in line with the rest of the framework and use the amplitude, but we need to make sure that this doesn't cost us resolution in the PID

This does in fact seem to matter. Resolution is better when using the integral rather than amplitude. Probably warrants more investigation when we have time.

Closing for lack of movement on this
